I have a notebook, which I believe belonged to a Japanese aircraft inspector for the first KI-60 prototype. It is dated June, 1940 and the only other english appearing in this notebook is "Inspector in Shisaku, Kaneko 1940 - June". My father brought this notebook back from Japan after his time there during the Occupation. He was a member of the 25th Infantry Division. The rest of the book contains day by day entries, in Japanese, from May thru June, 1940. There are many very detailed drawings of the aircraft's subassemblies, airfoils, structural members, tables, calculations, etc... including dimensions which appear to be in centimeters. Using these dimensions,they compare very closely to the length and wingspan of the first KI-60. Is there any interent in this notebook? I believe that it has historical value.
